Blockchain phones, such as those from Solana, face significant hurdles in gaining widespread acceptance, according to 0xTodd, a partner at Nothing Research. Despite the potential for returns through airdrops, these devices suffer from low hardware cost-effectiveness and concerns over new security chip technologies and potential backdoors. The flashy design of these phones also raises security risks, and pre-installed decentralized apps (DApps) offer little advantage, failing to create a compelling need for consumers. 0xTodd suggests that the focus should be on enhancing system-level security features and adopting a more discreet design, positioning these phones as secondary devices. He views blockchain phones as transitional products before major manufacturers fully embrace cryptocurrency, doubting the sustainability of this niche market.
